I have a small system that has happily run various versions of FBSD over the years. Currently it's on 6.1-R-p11. This morning I found /usr was out of disk space. I freed a little by clearing /usr/tmp, /usr/obj, and some log files I didn't need in /usr/var/log just to keep the "/usr: write failed, filesystem is full" from filling my screen. Next I checked my periodic.daily messages to see when the big increase happened. I found I lost nearly half of my space two days ago: Disk status: Filesystem 1K-blocks Used Avail Capacity Mounted on /dev/da0s1a 738318 101270 577984 15% / devfs 1 1 0 100% /dev /dev/stripe/user 6726926 3132434 3056338 51% /usr devfs 1 1 0 100% /usr/var/named/dev Today my "df -h" output looks like this: Filesystem Size Used Avail Capacity Mounted on /dev/da0s1a 721M 99M 564M 15% / devfs 1.0K 1.0K 0B 100% /dev /dev/stripe/user 6.4G 5.9G -9.5M 100% /usr devfs 1.0K 1.0K 0B 100% /usr/var/named/dev I have not done any upgrades or installations. So I tried tracking down the usage with du and got the following: blacksheep# du -r -c -d 1 -h /usr 2.0K /usr/.snap 41M /usr/sup 42M /usr/share 13M /usr/include 33M /usr/lib 92K /usr/libdata 17M /usr/libexec 903M /usr/local 26M /usr/bin 14M /usr/sbin 2.0K /usr/compat 186K /usr/games 12M /usr/home 15M /usr/var 10K /usr/tmp 6.0K /usr/X11R6 537M /usr/ports 428M /usr/src 2.0K /usr/obj 2.0G /usr 2.0G total So why does du report only 2.0 GB of usage while df reports over 6 GB? Where has my storage gone? Or do I not understand proper usage of du? Thanks for your help, Drew -- Be a Great Magician! Visit The Alchemist's Warehouse http://www.alchemistswarehouse.com
